FURNACE-CASING. l

To all whom t may concern:

Be it known that I, CEOIL L. Errs,a citii zen of the United States,residing at Van lVert, in the county of Van Wert and'State of Ohio, haveinvented certain new and useful Improvements in Furnace-Casings; .and ldo hereby declare the following to be Aa full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and I `use the same.

and a novel clasp for; holding the door in closed position.

Another obj ect ofthis invention is toV provide a furnace casing'asspecified which'is Y lined with asbestos'o'r analogous non-conductingmaterial and which hasa plurality of flexible members such as chainsor-the like connected to its upper endv for-'suspending the casing voverand about a furnace. Y

V A still further object lof the invention is to provide a novel form ofconnection for the adjacent edges of the front and rear casingsectons'which connections are so varranged that when theifront sectionsare locked together the said connections will be held againstrelative-movement 'but as -soonV as the frontv sections are freedthe'sanie may be swung outwardlyraway from the'furnace` and readilydisconnected fromv the rear sections. Y y

With the foregoing and other objects in view this'invention consists iiisuch novel features of construction, combination and arrangement ofparts as will behereina'fter more fully described, illustratedintheaccompanyingdrawings and claimed; v I

In describing the invention in detail reference will be had lto thevaccompanying drawings wherein like charactersdesignate like andcorresponding p arts throughout lthe several views, and 'in which Figure.1 is a' side elevation of the im-k proved furnace casing.

Y Fig. 5 is a verticaal section illustrating the application of myimproved casing to a furnace, andv i Fig." 6 is a'horizontal section onthe line i dicated by theV arrows. j

Referring tothe drawings by reference numerals,` 1 designates vthebodyand 2 the 6 6 of Fig. v5, looking in the direction indome of myimproved furnace casing. The

bodyV consists of a lower portion 3 and an upper. portion 4. The lowerportion Birests upon a base 5 and supports at its upper edge a ring'Tprovided with a horizontal flange 8. This portion embraces theringandthe flange 8 rests" upon the upper edge thereof.

t The upper` portion 4 also embracesthe ring 7 and it'v rests atitslower edge upon the flange 8, and it supports atitsupper edge a ring'9 which is `provided with a horizontal 'ange 1(4). Theupperfportioiifembraces the ring 9, land the flange 10 rests upon theupper edge thereof.' The' dome 2 embraces the Vlino` y9 yand restsjuponthe `flange. 10.l

ach of the bodyvportions 3 vand 4. comprises a front sectionll, a rearsection 12 vand side doors ffl-looks 14 are secured to Vthe sections 11adjacent their 'side edges.

Eyes 15, which .are secured to the doors 13 near the front "sidevfedgesthereof, engage the hooks 14 vto dctachably and-,hingedly connect thedoors 13vto the ,front sections 11-.- Straps 16 are pivotally connectedto the doors 13 adjacent the rearside edges thereof, and` they areprovidec'lk withjfa plurality of slots 17`to receive levers'lS. "Thelevers 18fare pivotally connected` to'thfe zrear sections'12 near thefront edgesthereof. :The straps 16 fand the levers 18 provide means 13are detachably.connectedftothe side edges of the rear sections y12 and'which are'fadaptl` ed, when operated' to connectthejre'ar edges of thedoorsl 13 to the rear sections 12, to`

pull the doors and' sections'intofnand-hold them in close" embracing fengagementl with the rings 7 and 9.

In Figs. 4 and 6 of thedrawingsthere is' illustrated a .modilied'form ofthe'means` for hingedly Vand detachably connecting the j l frontedgesofithe doors 13 tothe side edges of the front sections 11, and amodified form of the means for'detachably connecting the rear edges ofthe doors 13 to the side edges of the sections 12 and pulling the doorsand sections into and holding them in close emtbracingengagement withthe-rings 7 and 9. VThe modified form ofthe means for hing-v edly anddetachably connecting the doors 13, comprises loops 19`Which aresecuredto the front sections 11, near the edges thereof, and straps 2Osecuredto the doors 13 near the front edges thereof. The straps 2O areprovided with openings 21 to Vreceive the loops 19 and with tongues 22which enter the front ends of the loops 19. The modified form of themeans `for detachably connecting the doors V13'to. the rearsectons 12aiid'for pulling the doors and sections into and holdingv them in closeembracing enV Pgagement with the rings 7 and 9, comprises loops 23secured to the `doors 13 nearthe rear edges thereof, straps 24 securedt0 the rear sections 12 nearthe front edges thereof, levers 25 which areadapted to detach-V ably engage in the loops23, and yokes 26 which arepivotally connected to the straps 24 and to ,which the levers 25 arepivotally connected. n i i Y yBy jreference to' Figs. 3,"5 and.6 of thedrawings, it will be Seen that the vrearedges l Vof'the'frontsectionsllare rolledto pron vide beads 27.".7The; beads v27 Y are .locatedV on theouter sideof the sections 11, Vandgsecured to theinnersides of thesesections are strips 28 whichare-equal in'height to thev Vheight ofthesections and which extend rearwardly beyondthelrear edges ofthesections, and are overlapped by the frontV edges of the doors 13.'llhefront edges of the doors 13 are beaded as at 28a, and theirrearedges are beaded as at 29. The frontv edges of the rear sections'l2are beaded as Vat 30 and' have secured to their inner sides strips 31which extend Vforwardly beyond thefront edges thereof and which areover- Y lapped by the rear edges ofthe doors 13.

Thel strips 31 are equal. in heightl to the height ofthe sections 12vand doors-13. Al

metallicplate- 32 is secured to theinner side of eachV door13fin spacedVrelation thereto; lheseplates areequalin height to but areconsiderably'narrower than the doors.. A

packing 33' is secured to and betweenY each `ofthe doors 13 anditsfplater32. The front .sections'l'l' have secured theretoV in spacedrelationlto theirv innen sides metallic plates r34, wliichare equal inheight to the Yheight of the sections blut'V are'of greaterwidth,fthoseportions of the plates, vwhich project beyond the-sideedgesof-thelsections 11engaging the inner vsides of the'plates 32.v

VPackings Y35, lof ,asbestos arey secured to and f located vbetween thefront sections 11 and the platesl34. Y. The lrearsections 12 have portthe dome 2 after the removal` secured thereto in spaced relation totheir inner sides metallic plates 36. These plates are equal inheight tothe height of the sections 12 but are of greater width than suchsections. Those portions of the plates 36 which 'extend beyond the sideedgesof the rear'sections 12 engage-the inner sidesof the plates32.Packings 37 of asbestos are lo,-

Vcated between andl secured to the rear .sec-

tions l12 andthe plates v36.

The overlapping of the doors 13 and the strips 28 and 31, and theoverlapping of the plates 32, 34 and 36 establish air andV dust tightconnections between the meeting edges of the front sections 11, rearsections 12' and doors 13.r The asbestos packings prevent the loss ofheat through radiation fromthe body* of the casing.

The dome 2 is provided with openings 38 s Vwhich establishcommunicationbetween the.

furnace casing which may bereadily taken "down when it is desired torepair or clean the furnace and-as readily andquickly set Chains 39 laresecured at their up'.l Any one of the sections may be readily 1 andquickly removedwithout disturbing the other-sections. The casting isairand dustproofand it embodies a construction which is simple, durable andei'ective.
